Possibly a hopeless cause

I rooted my flex a while back and everything was going swimmingly. After attempting to update everything i seemed to have bricked it. I can turn it on and all it does is stay on the LG logo screen. I can put it into download mode if that helps. I am on sprint LG995 i believe. If anyone has any ideas on how to get my phone back I would greatly appreciate it. If anyone prefers, feel free to gimme a call or text me. 832-414-2730
Again. Any help is greatly appreciated
